The invention relates to hinges and more particularly to a hinge especially adapted for use upon the doors of automobiles.

An object of the-improvement is to provide a 5 hinge for automobile doors and the like in which the entire hinge is concealed when the door is in closed position, so that the hinge knuckle does not protrude beyond the outer surface of the automobile body as is common practice in automobile door construction.

Another object of the improvement is to provide a hinge which permits the door to swing open to a position which gives a larger door opening than is possible with the ordinary type of automobile door hinge.

A still further object is to provide the improved hinge with a stop for limiting the opening movement of the door, thus eliminating the usual stop means ordinarily provided upon automobile doors.

The above and other objects may be attained by constructing the improved hinge in the manner illustrated in the accompanying drawing, in which 4 .Figure 1 is a detached elevation of the hinge V showing the same in partially opened position;

Fig. 2, a plan sectional view through a door post and portion of an automobile door provided with the improved hinge showing the door in the open position; and

Fig. 3, a view similar to Fig. 2 showing the door in closed position. v

Similar numerals refer to T similar parts throughout the drawing.

The improved hinge includes three leaves indicated generally by the numerals 10, 11 and 12. The leaf 10 is provided with a plurality of aperturesl3 preferably countersunk to receive screws or the like for attaching the leaf to the door post of an automobile or the like which is indicated generally at 14.

At the outer edge of the leaf 10 is formed a pair .of hinge pin bearings 15 between which is received a, hinge pin bearing 16 formed upon the adjacent edge of the leaf 11, a hinge pin 17 being located through the bearings 15 and 16 providing a hinge knuckle or joint between the leaves 10 and 11.

The opposite edge of the leaf 11 may be provided with a pair of hinge pin bearings 18 between which is received the hinge pin bearing 19 formed upon the adjacent edge of the leaf 12, a hinge pin 20 being located through said bearings to provide a hinge knuckle or joint between the leaves 11 and 12.

, The hinge leaf 12 may be provided with a plurality of apertures 21, preferably countersunk as shown, to receive screws or the like for attaching said hinge leaf to the door of the automobile, a fragment of the hinged edge portion of which is indicated at 22.

Studs 23 are formed substantially midway of the upper and lower edges of the central leaf 11 and levers 24 are fulcrumed intermediate their ends upon said studs. The leaf 12 is provided'at its upper and lower edges with the angular flanges 25 provided with slots or grooves 26 in which are slidably located the studs or pins 27 carried by the outer ends of the levers 24.

The inner ends of these levers are pivotally 7 connected, as by the pins or studs 28, to the adjacent ends of links 29, the opposite ends of the links being pivotally mounted upon the studs 30 formed upon the upper and lower edges of the hinge leaf 10. 1

With the door in closed position, as shown in Fig. 3, the central hinge leaf 11 is folded upon the inner or door post leaf 10 while the outer or door leaf 12 is folded upon the middle leaf 11, and the entire hinge is entirely concealed so that the outside of the car body and door presents a smooth unbroken surface.

When the door is opened, as shown in Fig. 2, it will be seen that the door swings to a position where it obstructs the door opening materially less than with the usual form of automobile door hinge where the entire thickness of the door is extended across the door opening.

Itwill also be seen that the studs 27 upon the levers 24 operating in the slots or grooves 26 act as stops to limit the opening movement of the door so as to eliminate the necessity of providing additional stops for this purpose, while at the same time these levers and the parts associated therewith guide the hinge to the opened or closed position as the door is swung in either direction.

I claim:

1. A hinge including a door post leaf,-a central leaf hingedly connected at one edge to the door post leaf, 2. door leaf hingedly connected to the opposite edge of the central leaf, a guideway in the door leaf, a lever fulcrumed intermediate its ends upon the central leaf and having one end engaged in said guideway, and a link pivoted upon the door post leaf and pivotally connected to the other end of the lever.

2. A hinge including a door post leaf, a central leaf hingedly connected at one edge to the door post leaf, a door leaf hingedly connected to the opposite edge of the central leaf, an angular flange upon the door leaf provided with a slot, a lever fulcrumed intermediate its ends upon the central leaf and having a stud upon one end engaging said slot, and a link pivoted upon the door post leaf and pivotally connected to the other end of the lever.

3. A hinge including a door post leaf, a central leaf hingedly connected at one edge to the door a post leaf, a door leaf hingedly connected to the opposite edge of the central leaf, and a lever fulcrumed intermediate its ends upon the central leaf and having a sliding connection with the door
